A dough preparation machine includes a power unit, which drives, through rotational speed mechanism, a helical screw shaft that extends into a dough chamber so that the dough is compressed and pushed through rotation of the helical screw shaft to be discharged out of a jet nozzle mounted to the dough chamber. The dough chamber is provided, at a location above the helical screw shaft, with an auxiliary dough driver, which includes two movable blades that are opposite to each other and are selectively extendable outward and retractable inward. When one of the movable blades passes through a circular sidewall of dough chamber, it is pressed by the sidewall to get retracted inwardly and at the same time causing another one of the movable blades to extend outward to knead and poke dough. This process is cyclically repeated to efficiently knead the dough and prevent attachment of the dough.

The invention relates to a process and to a device for producing a pore-containing foodstuff, the matrix of which enclosing the pores contains starch. The process is characterized in that the dough is flowable, is admixed with pressure gas and is expanded through a nozzle into an adjacent flow-through channel so that the raw dough containing pressure gas foams in the flow-through channel. For warming of the foamed dough the flow-through channel has a section which is directly adjacent and has at least two electrodes arranged on its circumference for applying current to the foamed dough.

The present disclosure provides an apparatus for dispensing powdered material, including container for storing powdered material. The container includes inlet for receiving powdered material and outlet for dispensing powdered material. A screw conveyor member disposed within container, which includes a first end rotatably mounted on wall of container and a second end abuttingly positioned to outlet and is operable by actuator for conveying powdered material through outlet. A scattering member, which includes at least one obstruction, is coupled to outlet, for scattering powdered material from outlet during dispensing operation. A load sensor adapted to support container for measuring weight of container. A control module adapted to control operating speed of actuator to operate screw conveyor member in a plurality of rotating modes based on weight readings received from load sensor. The apparatus prevents formation of chunks while dispensing powdered substance and thereby ensure precise dispensing of powdered material.

A household mixer appliance having a mixing container with an inner surface and an open top, a drive arrangement and a hook. The hook has a sole attachment portion which, when attached to the drive arrangement, abuts a first inner surface portion of the mixing container inner surface. The sole attachment portion is attachable to the drive arrangement via a through hole in the first inner surface portion such that the hook is rotatable around a substantially horizontal axis of rotation within the mixing container when the hook is attached to the drive arrangement.

The invention relates to a rotary shaft for processing foodstuffs, the rotary shaft has a rotation axis and the rotary shaft comprises at least one tool which extends along the rotation axis. The tool has an airfoil profile such that the tool comprises a leading edge, a trailing edge, an upper surface and a lower surface. Further, the tool comprises at least one fluid channel between the mean camber line of the airfoil profile and the upper surface of the tool.

A dough penetration prevention device of a kneading machine includes a lip seal ring having seal ring wings integrally formed on an inner circumferential surface of the lip seal ring and fixed to a bearing housing, a head seal body on the sleeve in front of the bearing housing and fixed by a fixing body, to supply steam at a pressure level equal to the pressure of the kneading container into an opposite gap (t) between an outer circumferential surface of the sleeve and the lip seal ring, in opposition to the steam pressure of the kneading container attempting to penetrate into a gap (t) between the seal ring wings of the lip seal ring and the outer circumferential surface of the sleeve, and a steam supply and discharge part discharging condensed water to the outside while supplying steam to an inner circumferential surface of the head seal body.
